Hi Scott,

Thanks for your reply, and sorry that it took me so long to reply again.
I was in fact investigating and working out my own image, which now
works well (minus what's below, though I have workarounds which work
already: see below).

I've searched, and searched again, and didn't find this at all in the
growpart folder of cloud-initramfs. Is it possible that this is located
somewhere else, like in:
overlayroot/scripts/init-bottom/overlayroot

or in:
rescuevol/scripts/local-premount/rescuevol

???

It doesn't really make sense to me if it was there, but these are the
only place where I saw what you are talking about.

Maybe it's just that I got very frustrated by it, as I spent quite some
time to find out what happened. So forget it, and forgive me! :)

I'd appreciate if you help me to fix this trap thing, so it is clean again.

For the moment, I have this as a debian quilt patch. I will try to
produce something cleaner later on, so that you only have a patch to
apply, and then I'll open such bug (I don't want to consume your time
for Debian-specific things...).

You did reply, then we've talked about the fact that you had some
specific patches to live-build which were not documented anywhere, and
then you said you would. That's were we are at at the moment.
